Hello I'm the left's official spokesperson and I think I can clear up this confusion.
A woman is someone who wants to be a woman.
A husband is someone who wants to be a husband and has consent from the person they're a husband of.
Both of these words are identities, and letting people be who they want to be when it doesn't affect other people is one of the values of the left. So you can go ahead and extend this reasoning to all personal identities that don't harm others, and I think that answers your question.
Cause it's fucking bullshit
